How tight does the fuel pump lock ring have to be?



This picture of the lock ring was taken before I removed the lock ring and you can see the yellow marks that I made for reference points before removal.




I'm trying to finish up reinstalling everything and as you can see in this picture the yellow marks are not lined up.

To me it feels like I have the lock ring pretty tight but as you can see in the two comparison pictures that the lock ring reference marks are not in line from when I originally made the marks.



I have another issue where I can't get the left side fuel float to sit down in the hole flush. When I push down it seems like it's bind up against something? Any tips on getting this installed correctly?

I don't recall it being an issue on mine.
All the technical difficulty is on the right hand side.
I'm pretty sure it dropped straight back in, but it's been a while.

Is the float in a good orientation?
Is the big top rubber seal seated on the top of the float housing reasonably snug? I have heard these can stretch and deform slightly, which may hinder correct reinstallation - in which case you may need to replace it with the kit from Audi (assuming you can still buy it).

Interesting.

I not 100% sure I have the float in good orientation so I'm guessing that is my issue. From what I've remember, the top rubber seal is in good condition and is seated all the way to the top of the float housing. I'll take another try at it again when the weather cools down a bit.
